Absolute value: abs

Syntax

abs ( op )

Input parameters

op	the operand

Examples of valid syntaxes

abs ( DS_1 )
abs ( -5 )

Semantics for scalar operations

The operator abs calculates the absolute value of a number. For example:

abs ( -5.49 ) gives 5.49

abs ( 5.49 ) gives 5.49

Input parameters type

op

dataset { measure<number> _+ }
| component<number>
| number

Result type

result

dataset { measure<number [ value >= 0 ]> _+ }
| component<number [ value >= 0 ]>
| number [ value >= 0 ]

Additional Constraints

None.

Behavior

The operator has the behaviour of the “Operators applicable on one Scalar Value or Data Set or Data Set Component” (see the section “Typical behaviours of the ML Operators”).
